Something else that I didn't mention was that when attempting to flush
the queue using "sendmail -Rusername", along with the core dump, I received
the following error:
assertion botched: op->ov_magic == MAGIC
Solution:
I performed a wide range of checks and even got into dbx and trace.
Karl Vogel gave me a really neat command to run diags with:
echo test | /usr/lib/sendmail -d0-99.127 djp@inetinc.com > /tmp/sendmail.dmp
It didn't help but I'll keep it for later use.
Two people suggested that I had a malformed mail message in the queue. I
looked into this early on and moved pending messages out of the queue. The
mail somewhat worked for a while after cleaning things out but quickly
returned to the above errors.
Another suggestion was to look into my ISP, but since I have a direct
connection I was the only one to blame for my problem.
Ultimately the problem was me, I had modified my /etc/group file a day
earlier and inadvertently left a newline at the base of the file.
